"Norwood ran two shifts, and produced 57 cars per hour, or 912 per day. It took about two days (four shifts) for a body to go through the Fisher Body system, and another day and a half (three shifts) to go through the Chevrolet system."

Thanks - So, 3 shifts or 24 hours (assuming an 8 hour shift) to fully assemble and drive one Camaro away and 56 total hours of labor, including four 8 hour shifts at Fisher for the body build, for one Camaro.

Around 18 hours per car is considered competitive, just for assembly. Enormous strides have been made since then in automation in the Body and Paint shops; where a 60's Body Shop had 500-700 people per shift (most on spotweld guns), all welding and material handling is now robotic, and a typical Body Shop only has about 140 people, and only about half of those are production folks - the rest are skilled tradesmen tending to the robots. Paint Shops are about the same manpower comparison and level of automation - about the only manual operations today are sealing, and all spraying is automated; basecoats are waterborne, and clearcoat is 2-component catalyzed (and contains carcinogens) - no people in spray booths any more.

After the Paint Shop, Trim, Chassis, and Final Assembly operations are still mostly manual; selected operations (like windshield and backlite setting) are robotic, and many components are now received as ready-to-install "modules", with labor-intensive subassembly done by outside suppliers (seats, wheels/tires, instrument panels, bumper fascias, consoles, front and rear suspension assemblies, etc.).
